19Service Manual – SC6000 04 - Control System
Main Machine Controller
As the name implies, the Main Machine Controller (MMC) is the primary controller for the system. The
MMC functions as the primary interface for the operator, and directly or indirectly controls the functions of
the machine. Because the MMC controls the on/off function of the whole machine, it is always receiving logic
power through the 10 amp circuit breaker, but controls the status of the KSI relay to itself and the other
controllers.
The MMC communicates with the Power and Wheel Drive controllers through the CAN Bus. It also uses a
second CAN Bus to communicate with the optional telemetry module.
